The presentinvention relates to a method and apparatus for producing a spool of textile threads on a rotating spindle.

One of the objects of the invention is to provide means for winding a spool of textile threads or fibers on a rotating spindle at maximum speed, constant tension, and under easily controlled and varied conditions;

Another object is to provide means for varying the value of the ratio Ml, where t=the thread tension known to French spinners as ballon and T=the so-called tangent tension.

A further object is to provide means for eliminating the frictional electrical efiects produced during spinning.

An additional object 'is to provide a method for eliminating deleterious electrical efiects during spinning.

Still further objects will appear in the course of the detailed description now to be given with reference to the accompanying drawings in which:

Fig. 1 shows diagrammatically, the various tensions exerted on the thread, fiber or cord being spun; I

Fig. 2 represents an elevation partially in section, of one constructive embodiment of the invention;

Fig. 3 is a plan view of the structure shown in Fig. 2;

Fig. 4 is an elevation, partially in section, of the structure represented in Fig. 2;

Fig. 5 illustrates, in plan, the structure shown in Fig. 4;

Fig. 6 is a diagram showing how on the thread varies;

Fig. 7 is a section taken on line 7 7, Fig. 2, showing an electrical neutralizing device.

Referring to Figs. 1 to 3 and 7 of the drawings, there is shown a rotatable spindle 1 upon which a spool of thread 2 is to be wound,

tension terial covering surface 15 or flange 12.

I regulated, a plate 5 provided with any standard means (not shown) for being reciprocated back and forth in parallel to the axis I of spindle 1,--a pulley 6,a ball-bearing 7 supporting elements 5 and 6 in rotatable relation to one another,-a cable 9 anchored at one end to element 5 and frictionally embracing a predetermined arc of groove 8 in pulley 6,a weight 10 regulating the tension of cable 9,a tapering shell 11 threadedly en orifices 13 and 16 onto spool 2 and (0) slots 69 17 and 18 permitting orifices 13 and 16 to be easily threaded,a fixed or movable guidev 14 for directing thread 3 from cylinders 4.

towards an orifice 13 and positioned in line with spindle (Fig. 1) and means for neutralizing or discharging electricity generated by the frictional contact of thread 3 with orifices i3, 16 and exterior surface 15 of shell 11 comprising either (so) a lever 22 pivoted m at 23 and having a thickened extremity 27,

.a lining 28 adapted to polish thread 3 mov ing thereunder, an abutment 26, a grounded wire 39 for leading 0d the electricity generated and a spring 24 forcing lever 22 in direction 25 or (g) a flexible arm 29, lined at 28 to polish the thread moving thereunder and rigidly supported at 30, and a grounding wire 32 or (a) a coating or radioactive ma- -lhe operation of the hereinabove described assembly is practically self-evident. 'llhread coming from a cylinder passes through guide 14: in line with spindle 1, then through an orifice 13 over surface 15 into orifice l6 and onto spool 2, assemblies 22, 23, 2d, 26, 27, 28, 39 or 28, 29, 30, 39 or their radioactive equiva thread 3 adapted to be wound on spool 2 talents serving to discharge the electricity de- -and whose tension is to be controlled and veloped by frictibn. By varying the lateral 9a position of the orifice 13 chosen relatively to orifice 18 any desired ratio f Fig. 1 By varying the angle of torsion c:

(i. e. t e angle between orifices 13 18 in directions 20 or 21), the ratio mav be further modified (see Fig. 2)

e elements represented in Figs. i and 5 are designed to permit both variation of angle a and the length of the trajectory between orifice 13 and 18. Here, element 11 in the assem, bly represented in Figs. 2, 3 and 7 is replaced by a shell 31 threadedly engaging with pulley 6 and telescopically engaging with an exteriorly tapered extension 33 formin a driving fit therewith. A slide 35 admstably mounted on flange 34:01? extension 33, and having an orifice 13 and a slot 17 formed therethrough permits orifice 13 to be displaced to form any angle a desired with an orifice l6 traversing shell 31 and a second adjustable slide 36 permits the rotating assembly to be balanced for any position oi slide 35. To facilitate the threading of orifice 16 a slot 18 is formed in telescoping sh s and 33 and to maintain an align for relative longitudinal displacemer tter, there is provided pin 33 dly attached to shell 31 and slidely guid on an elongated slot 37 traversng she' The mode of operation L vice is very simple.

35 is displaced and h (a) mounting the late fit with flange 3% or slide or both which are magnetized so as remain fixed in any position of adjustment. To vary the length of the thread spiral extending between orifices 13 and 13, shell 33 is displaced telesco ically over shell 31 to vary the vertical distance between flange 34% and orifice 16 as desired. Fig. 6 shows how for a given angle as seen from Figs. 4 and 6, 90 is the maximum limit for an les Ba and B6 or their complements 0a and 6?) representing the inclination of thread 3 so that spiral thread lengths 1a and 16 may be varied by varying height between the limits Ho and HI). The shell 33 does not necessaril have to form a driving fit with shell 31 or, if either the former or the latter, or both are formed of ferrous metal and magnetized, they will re main inany position of relative adjustment.

The invention is not to be taken as limited to the particular form structure shown in an single figure; thus, elements 35 and 36 igs. 4 and 5) may be replaced by a plurality of holes 13 traversing a flange 12 as shown in Fig. 2 and conversely.

What I claim is:
